What is the title of the 2019 Netflix documentary series about Bill Gates?

The 2019 Netflix documentary series about Bill Gates is titled Inside Bill's Brain: Decoding Bill Gates.

The three-part series was directed by Davis Guggenheim, who also directed An Inconvenient Truth. It examines Gates’s childhood, Microsoft career, and later philanthropic work through interviews with Gates, family members, colleagues, and people involved in foundation projects.

The title refers to the series’ attempt to explore how Gates approaches complex problems rather than simply presenting a standard biography. Its episodes move between his personal history and initiatives involving global health, sanitation, and energy.

A common mix-up is confusing the series with documentaries about Microsoft or the Bill & Melinda Gates Foundation. Inside Bill's Brain is specifically a Netflix documentary series centered on Gates himself, and it premiered in September 2019.
